1. The orifice flowmeter should be equipped with a section of measuring tube during installation. At least one 10DN and a second 5DN straight pipe section should be maintained to improve measurement accuracy. 2. If valves need to be installed before and after the orifice flowmeter, it is best to choose a gate valve and

Serial Communication refers to a communication method that transmits data through a serial port. Data is transmitted bit by bit through data signal lines, ground wires, etc. Common serial ports include RS-232, RS-485 and RS-422. It should be noted that the serial port is only an interface standard. It specifies the electrical standard of the

Electromagnetic flowmeters, turbine flowmeters and vortex flowmeters are all commonly used flowmeters. They each have their own characteristics and usage environments. The following is their comparison: 1. Electromagnetic flowmeter: no mechanical moving parts, stable and accurate measurement, simple maintenance, but cannot measure non-conductive liquids Wide application range and large flow rate range Can measure liquids

The unstable output signal of the vortex flowmeter may be due to the following reasons: 1. Changes in the mass or pressure of the fluid: This may cause deviations in the measurement results of the flow meter. 2. Improper installation position: As mentioned above, if there is not a long enough straight pipe section or

Some common problems with instrument power supplies include unstable power supply, overheating of the power supply, too high or too low current, damaged power lines, etc. Here are some solutions to these problems: 1. The power supply is unstable: First check whether the power line is loose or damaged. You can also try to replace

An important feature of modern chemical production is the large-scale and highly automated production equipment. Automation is the basic condition and important guarantee for the safe operation, smooth operation and improvement of efficiency of production equipment. However, with the development of production and the improvement of automatic control level, the corrosion problem of chemical instruments
